Specification of Letters Patent.

Patented May a, 1915.

Application filedMay 9, 1913. Serial No. 766,574.

To all whom it may concern 7 Be it known that I, OSCAR L. OWEN, a citizen of the United States, residing at Whitinsville, in the county of Worcester and State of Massachusetts, have invented the following-described Improvements in Bobbin-Holders for Spoolers.

The improvement is a bobbin-holder for spoolers involving several features, one of which is that it is adapted to accommodate bobbins of different sizes, and another, that it is adapted to discharge the spent bobbin by a simple operation.

In the accompanying drawings I have shown the preferred form of the invention, incorporating both of these principal features.

In this drawing, Figure 1 is a side elevation of the holder; and Fig. 2 an end elevation thereof.

The frame or body of the device consists of a bracket provided with an attachment jaw 1, an upstanding arm 2 and an overhanging slotted arm 3, all of these parts being desirably cast as a single piece, as shown. The attachment jaw 1 supports the bracket on the holder rod of the spooler. On one side of the slotted arm 3 there is mounted a hinge-shaft 4:, held in lugs 5 on the arm, and forming the pivotal support for the bobbin cradle. The latter is formed in two parts, according to the present invention, both of which parts are counter-balanced and cooperate to carry the bobbin. The part marked 8 comprises a skeletonized pan-portion 9 on the end of a shank 10, bored to receive the shaft 4:, and a counter-weight 11 formed at the upper out-turned end of the shank. This part of the cradle can swing on the shaft through a limited are directly beneath the arm 3, its outward motion being limited by engagement of the shank 10 with a rib or abutment stop 12 cast on the arm 3. The other part of the cradle marked 8 comprises a skeletonized pan-portion 13, a shank 14., which is bored like the shank 10 to receive the shaft 4:, and a counter-weight 15 at the extreme upper and out-turned end of the shank. This counter-weight normally maintains the pan 13 in substantial registry with the pan 9, but its shank and counterweight are so arranged that the pan can have a wider range of swinging movement than the other suflicient to swing the pan quite the same as if the cradle pan were a single part, the center of gravity being accommodated to the particular size of bobbin. When the bobbin is spent, the operator presses the counter-weight or handle 15 toward the bracket arm 3, which withdraws the cradle-pan 13 from beneath the bobbin, thus dumping the latter from the holder into a box provided below. The two cradle parts, 8 and 8' are confined on the shaft 4 by means of set-screwed collars 17, 18 and 19, or like means, so that they can be set at varying distances apart to accommodate any desired length of bobbin, it being necessary to set these pans so as to preserve the center of gravity of the bobbin in an approximately central position which will keep it from jumping out of place during the unwinding. One of the cradle parts carries the bobbin abutment 16 and this part is preferably mounted so as to swing always in the same plane, the other part 8 being the adjustable member of the pair in the present case, although the other member or both members could be adjusted if desired. The bobbin is confined to the cradle by means of a tension guard, 6, which is pivoted to lugs 7 on the opposite side of the slotted arm. This guard is formed of round wire bent as indicated and hung from the lugs so that it can swing inwardly into contact with the bobbin, but cannot swing outwardly much beyond the free edge or edges of the cradle member. It will be understood that the guard is at least as long as the longest bobbin for which the device is designed and that the yarn from the bobbin is passed under its swinging edge or cross-bar so as to tend to press it against the bobbin.

I claim 1. A bobbin holder for spoolers comprising a bracket frame and a two-part cradle for the bobbin suspended thereon, one of said parts being capable of displacement from working position to dump the bobbin from the holder.

2. A bobbin holder for spoolers comprising a bracket frame, a two-part cradle suspended therefrom, the parts whereof are adapted for relative separation and vapproach in an endwise direction to accommo- Cir ' date bobbins of different size.

3. A bobbin holder for spoolers com- 7 prising a bracket frame, a two-part cradle thereon, one of said parts bearing the bobbin abutment and being relatively separable from the other part in an endWise direction.

' :4; 'A bobbin holder for spoolers comprising a frame, and a bobbin cradle comported and adjustable, relatively, in the direction'of the axis of the cradle, and a tension guard common to both parts of the bobbin. r

6. A bobbin holder for spoolers comprising two relatively adjustable parts, counterbalanced and provided With a tension guard whereby an unwinding bobbin may be confined therein,one of said parts being capable-ofioperation to discharge the bobbin therefrom. V

In testimony whereof, I have'signed" this specification in the-presenceof' two witnesses, p v 1 OSCAR L.-OWE'N. Witnesses: V
